I tried asking this in a different sub, but it got deleted, so trying here; if this is also the wrong place, I'm not sure where the right place is.

Working for an MSP, I have enterprise grade switches for my basement distribution and garage access switches, which came free from the e-cycling pile, but recent utility hikes have me rethinking things.

I'm currently running a HP 3500-48G-PoE+ yl Switch (J9311A) for the basement distribution switch, and a HP 3500-24G-PoE+ yl Switch (J9310A) as the garage access switch. My 2nd floor access switch is a USW-FLEX-MINI, though I'm looking to add a second one of these in the attic, both using PoE.

I try to keep one access switch in the same hardware class as the distribution switch in case of hardware failure. I don't really need 8 ports in the garage, but if the SHTF, I can do without internet in the garage, not so much in the house.

In the garage, the access switch is only hosting a PoE camera and access point, so there 8 ports is overkill, but redundancy.

After doing a hardware inventory, I can get by with 8 ports for the distribution switch, with at most 3 for PoE/PoE+, though I may need to move a raspberry Pi from the Distribution switch to an access switch.

I'm looking at PoE+ over straight PoE for future-proofing, Wifi 7 etc.

My current switches together idle at 226 watts, according to their spec sheets. I want to reduce that as a cost-saving measure.

I'm looking at the Netgear GS308EP and the TP-Link TL-SG108PE V5 as good enough replacements, as they both seem to do VLANs, which I use to keep IoT things on their own VLAN.

Anybody here have a preference, or something I haven't pondered which would be a better fit for my needs?

So, for the last couple decades, I've been lucky enough to be a professional geek doing server support for what is essentially an MSP. Every few years when they cycle their servers, I get a free upgrade from the e-cycling pile. That's worked great, but the third utility price increase in the as many years has me looking to rightsize my home server.

I'm currently running a Dell 720 which was a VDI server in its previous life, meaning 384G of memory and 40 cores of Xeon E5-2680, but I'm only using 20G of memory running about a dozen Docker containers, including Jellyfin; my load average is less than 1. I've been using Debian on that server, but I'm comfortable in any distro.

Unfortunately, the iDRAC says this is running between 200 and 250 watts at base. The hardware is vastly overspec'ed and I'd like to lower my power usage, if possible, as I'm certain it's not going to get any cheaper as time passes.

I also need to retire an old W10 box running BlueIris and migrate to a Frigate Docker container before October, because I'm not buying a Windows 11 machine just for that.

So I need a sanity check for my plan, as I've been on the server-side so long that my knowledge of desktop technology is sorely lacking, and I suspect some people here are running the EliteDesk 800 as a server.

I want to pick up an HP EliteDesk 800 5g SFF with an i9-9500 or i7-9700, such as: https://www.amazon.com/HP-EliteDesk-800-G5-Desktop/dp/B0BZ9J54WK

I'm not beholden to buying from Amazon, it was just the first link I found at a reasonable price.

I've chosen the EliteDesk because of the AMT KVM, and the SFF to add 3 1/2 HDDs.

I have DIMMs I can borrow or buy to get it to 48 or 64 gigs.

I'm using less than a TB of local storage on the 720, as it uses expensive 10k SAS drives, so most storage is NFS from the NAS. As a result I'm looking at a 1TB NVME for local OS storage.

I plan to use a couple 4TB spinning rust SATA drives for Frigate storage in the new system.

Are any of the M.2 slots on the board compatible with the Coral M.2 accelerators for Frigate? Preferably the Dual Edge variety? I'm having a hard time finding what kind of slots they are. I know I can get a PCI-E adapter, but native is better.

Is the i5-9500 enough, or should I pay the extra $150 for the i7-9700?

Is the i5/i7 iGPU strong enough for Jellyfin or should I be looking for a discrete GPU?

Those of you running one, what does your power consumption look like?

Am I going about this completely wrong?

Thanks in advance for any help.
